Getting a 400 bad request error trying to list recordings

Hi there,

I'm trying to retrieve a list of my recorded Zoom meetings using the APIs.  I have 2 accounts: a personal one and a work one.  It works for the personal account, but not the work one (for which I have Pro edition).

I submit a POST request to https://zoom.us/oauth/token and pass in:

HTTP Headers:

- Authorization = "Basic asdfasdfadf"

- Content-Type = "application/x-www-form-urlencoded"

HTTP Entity:

- grant_type = "account_credentials"

- account_id = "zxcvzxcvzxcv"

This returns the access_token which I can use in my next request which is:

GET https://api.zoom.us/v2/users/me/meetings

HTTP Headers:

- Authorization = "Bearer + access_token"

The above all works for my Personal Zoom account. 

However it fails with the following error, when I use it against my work account:

""Failed to execute the request, or the endpoint responded an error"

"Got response 400 - Bad Request from the endpoint"

Any ideas?
